GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 463,988, dated November24, 1891.

Application filed March 26, 1891.

To all whom it may concern.-

Be it known that I, CHARLES J. HARTLEY, of Decatur, in the county ofMacon and State of Illinois, have invented certain new and usefulImprovements in Grain-Meters, of which the following is a specification.

The object of this invention is to automatically measure grain.

The invention consists in the details of construction and combination ofparts hereinafter set forth and claimed, reference being made tothedrawin gs accompanying and forming a part of this specification.

Figure l is a front view of my meter connected with the discharge end ofa grain-elevator. Fig. 2 is a side view of the same with a side of thecasing removed and a part of the front of the casing broken away. Fig. 3is a rear view of the meter. Fig. t isa front View of the meter withpart of the mechanism removed. Fig. 5 is a vertical section on brokenline X in Fig. 2.

The outer casing is indicated by numeral 1, and it may be of any desiredsize, form, or proportion.

In Fig. 1 an elevator is shown at 2, and 3 is a sprocket-wh eel on thedrive-shaft of the elevator. Sprocket-wheel 5 rotates loosely on themeter-shaft A, and it is driven continuously when the meter is inoperation by chain 4. Cam 6 is rigidly attached to the face of wheel 5or is integral therewith. Lever 7 is pivotally connected with spider 9,and it has a lateral pin or projection on its swinging end, whichengages and is actuated by the recess of cam 6. Rod 8 connects pivotallywith lever 7 and with arm 11. Slide 10 has bearings in plate 12 and itprovides a fulcrum for arm 11. The arm has a packer or feeler 11 on itsinner end, and the bearing on which it pivots is rigid in the slide tosuch extent that the fulcrum cannot move vertically without moving theslide. The spider 9 is fixed on casing 1 and it provides a bearing foran end of shaft A. An arm lat is secured rigidly to the meter or theshaft thereof and carries the clutch-dog 15. (Seen in Figs. 2 and 4:.)The dog is adapted to engage the projection 10 on slide 10, and it hascatch 15* on the side next wheel 5 and pin 15 on the opposite side. Oam13 is secured to the casing and it affects Serial No. 386,461. (Nomodel.)

the dog through pin 15 in such mannerthat when the catch end of the dogfalls toward the shaft and the shaft begins to rotate the position willbe permanent until a complete rotation is nearly accomplished. Thesprocket-wheel 5 has lateral projections 5, as seen in Fig. 2, withwhich the clutch-dog engages when the slide is raised. The shaft 16 hashearings in the casing above the meter, and to it are rigidly connectedarms 17 and 19, one inside and theother outside the easing. Arm 17carries rake 18 immediately above the meter, and arm 19 carries a weightwhich presses down on the rake. Stop 20 regulates the descent of arm 19and it is adj ustable on the casing. The meter 21 has a principalcompartment 21 and auxiliary compartments 21, 21 and 21. The inner facesof the casing 24 and 25 conform to the circu- 7o lar heads of the meter,and one is cut away at 26 to permit the auxiliary compartment 21 todischarge its grain. A ratchet-wheel 22 is fixed on an end of shaft A,as seen in Fig. 3, and backlash-pawl 23 is pivoted on a pin connectedwith thecasing and is adapted to the ratchet-wheel.

In operation grain is supplied to the meter and the cam 6 onthecontinuously-rotating wheel 5 gives the packer 11" an oscillating 8omovement by means of a cam 6, lever 7, and rod 8. When the largecompartment is filled and the grain heaps above it to a certain extent,the packer will be unable to descend and I the slide 10 will be raised,thereby releasing 8 5' dog 15 and permitting its catch end to fall inclutch witha projection of the wheel. As the meter is carried around bythe clutch the pin 15 will follow the cam-groove and preventdisengagement and the accumulated grain will be received by theauxiliary compartments. As the grain descends in the meter-box the slide10 descends also, and by the time the rotation is completed theprojection 1O will be in position to arrest the motion of the 5 dog andthrow it out of clutch with the wheel.

The combined capacity of the several compartments constitutes a unit ofmeasure that is to say, the several compartments jointly hold a bushelor other unit of meas- 10o urement. WVhen it is desired to vary this tocompensate for variations in the weight of grain or for other reasons,the rake 18 is so adjusted by means of stop 20 that the diameter of themeter is practically increased 'or diminished and the capacity thereofcorrespondingly varied.

I claim- 1. In a grain-meter, the combination of a meter, a slideholding the meter in position to receive the grain, and a packer-ar1npivoted in the slide and adapted to be continuously oscillated, wherebyan accumulation of grain will cause the packer-arm to raise the slideand permit the meter to discharge, as set forth.

2. In a grain-meter, the combination of a rotary meter, a slideholdingthe meter in position to receive the grain, a drive -wheelmounted loosely on the meter shaft and adapted to be continuouslyrotated, a packerarm pivoted in the slide and connected with a cam onthe drive-Wheel, and a clutch-dog connected with the meter and adaptedto engage the drive-Wheel when the slide is raised, as set forth.

3. The combination of the rotary meter, the

drive-Wheel on the meter-shaft, the cam on the drive-Wheel, thepacker-arm actuated by the cam on the drive-wheel, the slide acting as astop for the meter and providinga pivot for the packer-arm, theclutch-dog connected with the meter and adapted to engage thedrive-Wheel, the cam on the meter-casing, and the pin on the clutch-dogadapted to the cam of the casing, as set forth.

at. A circular meter adapted to make a complete rotation at eachoperation and having a principal compartment inside chords of the circleof the meter and auxiliary compartments outside such chords, as setforth.

5. The combination, with the rotary meter, of rake 18, the weighted arm19, and the adjustable stop 20, as set forth.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.

CHARLES J. HARTLEY.
